An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-23853 in the wild and no public exploit code.\n\nAffected product: Bosch CPP Firmware. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-23853/ (Markdown: https://insights.sbomify.com/CVE-2021-23853/index.md)","id":"CVE-2021-23853","markdown":"https://insights.sbomify.com/CVE-2021-23853/index.md","name":"CVE-2021-23853","record":{"aliases":["GHSA-9f38-8856-g696"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Bosch IP camera firmware","requires_auth":"none","summary":"Attackers can inject arbitrary HTTP headers via crafted URLs in Bosch IP cameras, potentially affecting request handling.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"bosch","cpe":[{"product":"cpp13_firmware","vendor":"bosch"},{"product":"cpp4_firmware","vendor":"bosch"},{"product":"cpp6_firmware","vendor":"bosch"},{"product":"cpp7.3_firmware","vendor":"bosch"},{"product":"cpp7_firmware","vendor":"bosch"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In Bosch IP cameras, improper validation of the HTTP header allows an attacker to inject arbitrary HTTP headers through crafted URLs.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Improper Input Validation of HTTP Headers","id":"CVE-2021-23853","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Reflected XSS in page parameter","id":"CVE-2021-23854"},"packages":[],"prev":{"headline":"Denial of Service (DoS) due to invalid web parameter","id":"CVE-2021-23852"},"products":["CPP Firmware"],"published":"2021-06-09","related":[{"cvss_score":8.3,"headline":"Reflected XSS in URL handler","id":"CVE-2021-23848","kev_date_added":null,"published":"2021-06-09"},{"cvss_score":8.3,"headline":"Reflected XSS in page parameter","id":"CVE-2021-23854","kev_date_added":null,"published":"2021-06-09"},{"cvss_score":7.2,"headline":"Command injection in Camera Firmware","id":"CVE-2023-39509","kev_date_added":null,"published":"2023-12-18"},{"cvss_score":5.3,"headline":"Information disclosure in Camera Firmware","id":"CVE-2022-41677","kev_date_added":null,"published":"2023-12-18"},{"cvss_score":4.9,"headline":"Denial of service in Camera Firmware","id":"CVE-2023-32229","kev_date_added":null,"published":"2023-06-15"},{"cvss_score":4.9,"headline":"Denial of Service (DoS) due to invalid web parameter","id":"CVE-2021-23852","kev_date_added":null,"published":"2021-06-09"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["Bosch"]},"summary":"Attackers can inject arbitrary HTTP headers via crafted URLs in Bosch IP cameras, potentially affecting request handling.","url":"https://insights.sbomify.com/CVE-2021-23853/"}
